Furthermore, one side of the guide plate, which is attached to the inner wall of the inner cavity, is provided with a guide cavity, one side of the guide cavity is arc-shaped and communicated with the outer cavity, and the other side of the guide cavity is elliptic arc-shaped.

Furthermore, a conical flow guide cover and a guide pipe penetrating through the conical flow guide cover are arranged in the evaporation chamber, the lower end of the guide pipe is communicated with the inner cavity, and the upper end of the guide pipe is aligned to the top of the conical flow guide cover.

Furthermore, a plurality of through holes are uniformly distributed on the conical diversion cover.

Furthermore, the heating chamber is communicated with the circulating pump through a pipeline, a condensed water discharge pipe is arranged on the pipeline, and a valve is arranged on the condensed water discharge pipe.

After the technical scheme is adopted, steam enters the outer cavity bottom of the heating chamber from the steam inlet pipe and gradually spreads to the whole outer cavity, feed liquid enters the inner cavity of the heating chamber from the feed pipe through the circulating pump, enters the gap of the penultimate guide plate from the gap of the bottommost guide plate and is gradually filled in the whole inner cavity, then is sprayed on the conical guide cover through the guide pipe, and finally enters the circulating pump through the circulating pipe to complete one-time circulation, because the direction of one side of each two adjacent guide plates with the elliptical arc shape is opposite, the contact time of the feed liquid with the steam is greatly increased when the feed liquid passes through the heating chamber, the arrangement of the guide cavity enables the steam to enter the guide cavity, the contact area of the feed liquid with the steam through the guide plates is greatly increased, the evaporation efficiency is higher, in addition, the contact area of the feed liquid with the steam is, so that the feed liquid can be subjected to up-to-standard concentrated liquid only through a few circulations and is finally discharged through a discharge pipe.
